I just update the system through yum update command.
After that, I reboot the VPS, then, lost the connection to this VPS and web site.
- Can not access the web site on it from browser.
- Can not access the VPS through ssh
- Can not access the VPS through Serial Console.
I create a ticket on servermania support. The support team replied in 20 minutes.
After two conversation between Andrew and me.
He told me that the problem is:
The yum update had broken the iprouting on the OS which caused the venet to not come up.
